Efficient DOM manipulation is key to fast and responsive websites. Traditional methods of handling the DOM can slow down complex web pages. React's Virtual DOM offers a solution by minimizing updates to only necessary parts, significantly improving performance. React's Diffing Algorithm identifies changes between versions of the Virtual DOM, ensuring efficient updates. For specific tasks like focusing on an input or scrolling, React provides the useRef Hook for direct DOM manipulation. By leveraging these techniques, developers can build smoother and faster applications.

Okay read but this article is quite patchy. I don’t know if the author proof-read this before posting.

Very good explanation of how React checks if the DOM needs updating and how the diffing works

Great introductory piece. Less unknown unknowns for me :D
